Neuronal networks, similar to many other complex systems, self-organize into fascinating emergent states that are not only visually compelling, but also vital for the proper functioning of the brain. Synchronous spatiotemporal patterns, for example, play an important role in neuronal communication and plasticity, and in various cognitive processes. Recent research has shown that the coexistence of coherent and incoherent states, known as chimera states or simply chimeras, is particularly important and characteristic for neuronal systems. Chimeras have also been linked to the Parkinson's disease, epileptic seizures, and even to schizophrenia. The emergence of this unique collective behavior is due to diverse factors that characterize neuronal dynamics and the functioning of the brain in general, including neural bumps and unihemispheric slow-wave sleep in some aquatic mammals. Since their discovery, chimera states have attracted ample attention of researchers that work at the interface of physics and life sciences. We here review contemporary research dedicated to chimeras in neuronal networks, focusing on the relevance of different synaptic connections, and on the effects of different network structures and coupling setups. We also cover the emergence of different types of chimera states, we highlight their relevance in other related physical and biological systems, and we outline promising research directions for the future, including possibilities for experimental verification.

神经元网络中的嵌合体状态:综述

与许多其他复杂系统类似,神经元网络会自​​我组织成令人着迷的新兴状态,这些状态不仅在视觉上引人注目,而且对于大脑的正常运转至关重要。例如,同步时空模式在神经元交流和可塑性以及各种认知过程中起着重要作用。最近的研究表明,相干态和非相干态的共存,被称为嵌合体状态或简称嵌合体,对于神经元系统特别重要且具有特征。嵌合体也与帕金森氏病,癫痫发作甚至精神分裂症有关。这种独特的集体行为的出现是由于表征神经元动力学和整个大脑功能的各种因素所致,包括某些水生哺乳动物的神经颠簸和单半球慢波睡眠。自发现以来,嵌合体状态吸引了从事物理学和生命科学界研究的研究人员的广泛关注。在这里,我们回顾了致力于神经元网络中嵌合体的当代研究,重点是不同突触连接的相关性以及不同网络结构和耦合设置的影响。我们还将介绍不同类型的嵌合体状态的出现,强调它们在其他相关物理和生物系统中的相关性,并概述未来的有希望的研究方向,包括进行实验验证的可能性。嵌合体状态已经吸引了从事物理学和生命科学界研究的研究人员的广泛关注。在这里,我们回顾了致力于神经元网络中嵌合体的当代研究,重点是不同突触连接的相关性以及不同网络结构和耦合设置的影响。我们还将介绍不同类型的嵌合体状态的出现,强调它们在其他相关物理和生物系统中的相关性,并概述未来的有希望的研究方向,包括进行实验验证的可能性。嵌合体状态已经吸引了从事物理学和生命科学界研究的研究人员的广泛关注。在这里,我们回顾了致力于神经元网络中嵌合体的当代研究,重点是不同突触连接的相关性以及不同网络结构和耦合设置的影响。我们还将介绍不同类型的嵌合体状态的出现,强调它们在其他相关物理和生物系统中的相关性,并概述未来的有希望的研究方向,包括进行实验验证的可能性。
